Best bets: Tom Cruise leaps into the future in 'Oblivion'

Some serious stuff this week, from a sci-fi movie looking at a devastated Earth to Quentin Tarantino's Oscar-winning slavery movie to a new look at a political scandal.

TUESDAY: 'Django Unchained' on home videoQuentin Tarantino has won two best screenplay Oscars, one for the legendary "Pulp Fiction" and one for "Django Unchained." The controversial "Django" comes to home video this week, and whether you want to see what all the fuss is about or need to see it again, now's the time. Christoph Waltz won the Oscar for best supporting actor for his role as Dr. King Schultz, a German-born bounty hunter who teams up with the slave Django (Jamie Foxx). The two set out to bring in numerous wanted men while searching for Django's sold-away wife (Kerry Washington). The film's filled with Tarantino's legendary action, extreme violence and snappy dialogue -- it's not for everyone, but there's no denying its impact. (On home video April 16.)

FRIDAY: 'Oblivion'The first of three devastated Earth films opens this week. In "Oblivon," Tom Cruise stars as a drone mechanic who believes he's helping to scrape the final resources from an abandoned planet. But when he finds a woman in a crashed spaceship and is kidnapped by a team led by Morgan Freeman, he learns that he's been working under false premises all along, and may have no real idea what's going on in his world. Cruise has re-established himself as a believable action hero thanks to "Mission: Impossible" and "Jack Reacher," and this plot is intriguing. (Opens April 19.)

SUNDAY: 'All the President's Men Revisited'The Watergate scandal that led to President Richard M. Nixon resigning was 40 years ago, and the landmark movie, "All the President's Men," came out in 1976. Now Robert Redford, who played Washington Post reporter Bob Woodward in the film, has taken another look at that dramatic moment in American history with "All the President's Men Revisited." Redford's co-star, Dustin Hoffman, as well as the real Woodward and partner Carl Bernstein, are in the new film, along with Jon Stewart, Rachel Maddow and others. (April 21, 8 p.m., Discovery Channel)
